Lori and I got up to San Francisco with just enough time to eat lunch before her appointment. We grabbed some sandwiches and then walked up to the top of Alta Park to check out the view. Down the street a crew was replacing the roof on a Tudor Revival that had a seriously steep pitch. This guy was at least four floors up and was walking the peaks like he was down on the sidewalk below. I’m not terribly afraid of heights but that would have had me pretty uncomfortable, and I don’t think I would have been up there without being tied off on a rope.
